ABSTRACT:
An aircraft having, for example, a tailplane (4, 5) at least part of which is movable with reference to a fuselage (1) to effect control requires the control effect to be enhanced in a certain control position. Accordingly, fixed vanes (8, 9) are provided on the fuselage forward of the tailplane to form a substantially continuous leading edge root extension only when the tailplane is in a given control position.
